Question Copying Windows to new drive issue.

[Kickstart90]

I built my PC last week, first one I've done in over 10 yrs. Everything went smoothly other than copying windows over. I used Macrium Reflect to copy from my old mechanical drive to my new SSD. The SSD is 1TB and the older drive is 250gb. It must have partitioned the drive because all I see now is, windows showing my new 1TB SSD is 250GB. How can I access the rest of my storage? Also windows is telling me my product ID is non existent.

You are lucky your PC even boots if you are using a Windows install from a previous build. A new motherboard is best when paired with a clean OS install.

New PC + different drive...you're lucky it boots at all.

What happened was that the clone process simply made a partition of exactly the same size as the original drive.
The rest of it is simply Unallocated space.

What type of drive is the new SSD? Make/model, please.
